The triode with increased protection against vibrations - 6S19P-V is widely used to regulate and stabilize the voltage in the circuits of various radio technical devices. The radio lamp is made in the form of a glass cylindrical body with nine rigid contacts on its base. 

Basic technical characteristics
• Voltage recommended for supply to the anode: 110 V.
• Maximum output power at 200 V anode voltage: 11 W.
• Nominal and maximum current in the anode circuit: 95/140 mA.
• Average current in the glow circuit: 1 A.
• Internal active resistance of the triode: 300 ohms.
• Input, pass-through, output electrical capacity of the lamp: 6.5/8/2.5 pF.
